Analysis for time-dependent flow of Carreau nanofluid over an accelerating surface with gyrotactic microorganisms: Model for extrusion systems

Abstract

Recent progress in nanotechnology and nanoscience has attended the researchers' interest due to its inspiring industrial and technological applications. This contribution investigates the bioconvection flow of Carreau fluid over a periodically moving stretched surface with important feature of magnetic field and thermal radiation. Bioconvection in non-Newtonian nanofluid is utilized with sustaining the joint features of buoyancy and magnetic forces. In addition, thermal radiation consequences are summarized in the energy equation while further computations have been operated under ''one parametric approach.'' The attended problem is contested with a famous convergent technique having excellent accuracy. A comprehensive graphical approach is constituted to describe the thermo-physical features of interesting physical parameters. The reported results may use in enhancement of extrusion system, bio-fuels, and biotechnology.

Overlapping grid spectral collocation approach for electrical MHD bioconvection Darcy–Forchheimer flow of a Carreau–Yasuda nanoliquid over a periodically accelerating surface

“…Thus, inclusion of bioconvection has a tendency of minimizing the velocity field remarkably. Similar behavior of buoyancy ratio and bioconvection Rayleigh parameters was noted by Khan et al 55,59 who neglected porous medium and electric field features. the temperature, hence leading to a thin thermal boundary layer.…”

Bio-Convection Effects on Prandtl Hybrid Nanofluid Flow with Chemical Reaction and Motile Microorganism over a Stretching Sheet

“…Waqas et al [27] studied microorganisms in an electrically conductive viscous nanofluid on a porous stretched disc. Khan and Shehzad [28] investigated the Carreau nanofluid bioconvection flow across an expanding surface. Balla et al [29] explored the bioconvection of oxytactic bacteria in a porous square enclosure using thermal radiation.…”

Influence of Chemically Reacting Ferromagnetic Carreau Nanofluid over a Stretched Sheet with Magnetic Dipole and Viscous Dissipation

“…2D MHD Carreau fluid [18,19] analysis of gyrotactic microorganisms [18,20] over a slendering sheet was investigated for variable thickness and slenderness parameters using Runge-Kutta-based Newton's scheme. Multiple slip effects were taken in account with Soret and Dufour effects for the controlling process of the mass and heat transferring and exerted the modifying and controlling influences on mass and heat transfer rate for distinct numbers of slendering parameters.…”
